At a given instant, the blood pressure in the heart is 1.4 x 104 Pa. If an artery in the brain is 0.37 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

(a) Calculate the absolute pressure at the bottom of a fresh-water lake at a depth of 22.4 m. Assume the density of the water is 1.00 ✕ 103 kg/m3 and the air above is at a pressure of 101.3 kPa. Pa(b) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 36.0 cm? N

The pressure exerted by a phonograph needle on a record is surprisingly large. If the equivalent of 1.50 g is supported by a needle, the tip of which is a circle 0.150 mm in radius, what pressure is exerted on the record in N/m2?

A vertical test tube has 1 cm of oil floating (density of 900 kg/m3 ) on 6 cm of seawater (density = 1030 kg/m3).   Find the pressure at the bottom of the tube due to the fluids on it.  Express your answer in kPa.

A submarine is currently being developed to take tourists on sightseeing trips to tropical coral reefs. According to engineering guidelines the sub must be able to withstand a pressure of 10.09 N per square millimeter. To what depth can the submarine safely descend in seawater? Take atmospheric pressure to be 101,500 Pa and the density of seawater as 1025 kg/m3. Note: Be sure to convert the pressure to in N/m2

A particular table has six identical legs, and the surface area at the bottom of each leg in contact with the floor is 2.40 x 104 m². Assume the legs are uniformly spaced around the table, and the mass of the table is uniformly distributed with respect to the legs. The total mass of the table is 47.7 kg. What is the pressure (in Pa) on the bottom of each table leg (due to the floor alone, ignoring atmospheric pressure)? Pa

An otter is swimming in the deep area of his tank at the zoo. The surface area of the otter's back is A = 0.45 m², and you may assume that his back is essentially flat.
